Dear K.Supakit,
The actual cost including freight, customs clearance, import duty, and inland cost is difficult to confirm right away. Those actual cost will be plus 5% service charge and deduct from your payment accordingly by using “Debit Note” process. Anyway, we will try to order such additional parts to ship with our normal order so that the shipping cost will not be so high. You can refer ex-factory price as below e-mail. The lead time will be 1-2 months from order confirmation.
My suggestion is to confirm the order quantity in urgent as we are going to place the order within this week so that we can combine the shipment together. After part arrival, we will process “Debit Note” to deduct your payment afterwards.
